CAN-DRAINING MACHINE.

Application filed November 6, 1924. Serial No. #48402.

To all whom it may concern:

Be it known that I, Gnonon D. GARDNER. a citizen of the United States, and a resident of the city of San Jose. county of Santa Clara. State of California, have made a new and useful invention-*to wit, Improvements in Can-Draining Machines: and I do hereby declare the following to be a full, clear, concise, and exact description of the same.

This invention relates particularly to a machine for draining fluid from open ended vessels such as cans, bottles and the like.

An object of the invention is to provide a U121Cl1i1'18 in which open ended containers,

such as cans in which "food-stufi's-are to be preserved, may be drained of fluid either before or after the containers are filled with food-stuffs or prior to filling said containers with syrup or other preserving fluid.

A further object of the invention is to provide a can draining machine to which the cansare delivered to the draining machine on a substantially horizontal plane, and subjected to a draining operation through a substantially horizontal plane by said draining machine. and discharged onto a substantially horizontal surface.

A still further object of the invention relates to a can draining machine having can holders thereon, to'which cans to be drained are delivered open end up and after being received in said can holders. through the operation thereof. are inverted open end down. or im'erted into some other angular position with the open end of the can down. and at the completion of the draining operation are delivered open end up to a suitable conveyor.

' Other objects of the invention are to provide can supports on a can draining machine which may be revolved into any predetermined position in conjunction with perforated can covers to be placed over the open ends of the cans, at the commencement of the draining operation for the purpose of bold 'ing the cans on the can holders and removed from the open ends of said cans at the completion of the draining operation, to permit the removal of the cans from the can holders; and to provide a can draining machine that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation. and facility and convenience in use and general etficiency.

In this specification and the annexed drawings, the invention is illustrated in the? ing the description, it"is desired to cover the invention in whatsoever form it may be embodied. In the accompanying four sheets of drawg q I I Fig. 1 represents a side elevation of a can draining machine, constructed in accordance with my invention. r I

In order to hold the hollow:shafts23 and shafts into whatever positions thesame" may be placed by'thel respective bevelgears f 29 37' iI'havearranged depressions-50 and in the cam gu1de 4'8, and depresthe gear'racks42 and 43 for governing and controlllng the operation and actua sions 52- and 53- in thecam guide 49 which said depressions; in conjunction with the raised portions of the 10am guidesnserveftoo hold-the hollow shafts 231'andshafts 35in either of. the horizontal or vertical orangu-v lar positions into which the same are ro-v ice fated by the'hevel gears 29 and 37 mesh-Q with the toothed portions lof rthe gear racks42 and 431 I T i 7 On the ends of the shafts 35," eccentric members are secured and on" which cc:- centric straps- 55am operativelymounted. The free ends of the straps 55 project above that portion of thecan l1older1brackets26 'vihich isopposite t0 the can. holder. platforms 27. On the upper portion ofthe can holder bracket-s26 projecting lugs 5,6"are formed to which the arms 57" of theperforated can coiers "58 are pivotally secured at Ball projections '60are arranged on thecorerarms '57,and the ball ends of said projections arev eccentric straps -3o iieiiolves the eecentric members 54 therearound to cause ztTQOlpIOCatlIlg movement of the'straps-55, whlch,"on=:account of be:

operatively eonfined in open- 'v J'sgsGl' formed in the extended ends of the V Rotation oft-he shaft-s mechanisms, cause the can covers 58 to be moved into closed engagement with the open ends of the cans, at the beginning of the can draining operation, and to be locked into engagement therewith during said operation through the action of the cams 40 and cam guides 49. The can covers 58 are locked over the open ends of the cans during the time that the cans are inverted for draining purposes, and said covers are released from engagement with the open ends of the cans at the'completion of the can draining operation to permit the drained cans being removed from the can holders.

The rotation of the can holder by the gear 29 and racks 44 and 45 throughout two separate arcs of 180 each, is synchronously accompanied by rotation of the cover eccentric 54 through two separate arcs of movement of 180 each. The cam- 40 on the shaft connected to the eccentric 54 has but one flat face and is turned through 360 at each operation, whereas the cam on the can holder has two fiat faces and is turned through two separate arcs of'180 each at each operation.

In order to supply cans tothecan holders for draining purposes, I have provided an endless belt 63 having its-upper surface arranged substantially horizontal, and level with the end of the'platform 12'mounted on the edge of the bowl 2. The cans are placed indiscriminately upon the belt 63 and as the cans near the draining machine, one side thereof is forced into engagement with the revolving spiral feed screw 64 which serves to space the cans apart a predetermined distance, and to advance them into position between the guide member 65 and timer 66. Thetimer 66 is fixedly mounted on the upper end of a shaft 67 journaled in bearings 68 and 69 secured to the pedestal base 1. A bevel gear 70 is secured to the lower end of the shaft 67 and said bevel gear meshes with a companion bevel gear 71 mounted on the end of a driving shaft 72, which is supported in bearings 73 and 74 secured to the base 1. The driving shaft 72 is connected to a source of driving-power, not shown. The timer 66 is rotated in unison with the revolving of the can holders 27, so that said can holders will be supplied with cans open end up after the can holders come into registering communica-' tion with the space between the can guide 65 and timer 66. The cans are delivered onto the can holders in the vertical position open end up. As the can holders commence to revolve on a horizontal plane about the axis of the drive shaft ,6, the first operation that takes place is that of the can covers 58 closing onto the open ends of the cans, This operation is brought about by the bevel gears 37 on the shafts 35 engaging the gear rack 46, andbeing revolve t eby'which action lowers the can covers into engagement. with the open ends of the cans. In unison with the lowering movement of the can covers, the cams 40, on the shafts 35, ride off of the elevated portion of the cam guide 49 into the can covers in either the fullyopened or 7 fully closed positions. Duringthe time that the circular peripheries of thecams 40 enter the cam guide depression 52 the can covers are moving into or from the fully opened or fully closed positions Immediately after the cove1s are closed onto the cans, the bevel gears 29 are moved into engagement with the gear rack 44, to rotate the can holders about the axes of. the shafts 35. Synchronouslyv with the bevel gears 29 and rack 44 becoming enmeshed, the cams 33 connected tosaid bevel gears 29- move from the elevated portion of the cam guide 48 into the depression 50 therein. The cams33 serve to lock the can holders in a vertical position,

and during the period thatthe cams 33 en-v counter the depression 50, in the cam guide 48, the can holders are permitted to revolve. Immediately after the can holders complete the turning operation, the cams 33 rise. out of the depression 50 up onto :the. elevated portion of the guide way 48 to'hold thecan holders in a vertical position, preferably with the open end ofthe can down,- to permit the draining thereof. The can holders continue to move around the axis of the shaft 6 in an inverted position, until such time as the bevel gears 29 engage the gear rack 45-and the cams 33 enter in the depres sion 51 to ermit the can holders to be turned over to p ace the open ends of said cans up. Upon the starting of the can holders turning operation the bevel gears 37 engage thegcar rack 47 and the cams 40 encounter the cam depression '53 which permits the covers 58 to be elevated away from the open ends of the cans. During the remainder of.

the draining operation the can holders position the cans in a vertical position open end up with the can cover open. "Atthe completion of the drain-ing operation the cans are automatically removed from the can holders by a timer 75 fixedly mounted-on the end of a shaft 76, journaled in bearings 77 and 78 mounted on the base 1; The lower end of the shaft 76 is provided with a bevel gear 79 thereon meshing with a companion bevel gear 80 fixed on the driving shaft 72; The timer 75 moves the cans out of the can holders into engagementwith a'curved can guide 81fromwhich the cans are moved into engagement with a spiral feed screw 82 by mean of which the cans are advanced from the "platform 12 to the syrupingmachine in- V 'dicated' at83 or into placement With any other desired form ofapparatus. The draining operation oftheicans, as Well'as the de livery andidischarge of the cans to the drain- 7 ing' machine; 7 is carried on throughout a substantially horizontalplane, in contra distinction to convent1onal types of can draining machines in which the cans are disserve to hold the cans at an angle 'to the-yer 7 tom end up during tical, :Whereby said 1 cans might be drained angularly either of two directions. Although I have shown and described cams whichwillmaintain the can holders in the verticallposition for draining purposes 'I do not Wish to be limited exclusively thereto, inasmuch" as. the form of .camshown in Fig. 10 wouldserve to cause the functioning of my invention inan equally desirable manner.
